EXCELLENT Based on 44 reviews Tom Morgan18/07/2025Trustindex verifies that the original source of the review is Google. The aluminium windows from this lot are bloody brilliant at keeping the noise and cold out. Barely hear a peep from outside, and the heating bills have dropped a fair bit. The team knew their stuff, turned up on time, and did a proper job. If you’re after comfort and saving a few quid, give ’em a bell. Danny Thomson17/07/2025Trustindex verifies that the original source of the review is Google. Sorted me out with a new front door sharpish. Quality’s top-notch, and measured up within days. Wouldn’t hesitate to recommend them. Elijah Barrett17/07/2025Trustindex verifies that the original source of the review is Google. Durajoin fitted aluminium windows last month. Proper made up with ’em - look smart, keep the noise out, and the insulation’s spot on. Cheers, lads! Matthew Burton11/07/2025Trustindex verifies that the original source of the review is Google. Just had a new front door fitted in my flat. Price was well reasonable, fitted to a proper high standard, and the communication was bang on throughout. Popped over to their workshop to chat about what I wanted, and the lads really knew their stuff about handles, locks, glass and all that - even helped me decide between PVC and composite. Cheers!
